About Me

Hello! I'm an Assistant Professor in the Department of Industrial Engineering and Management at National Yang Ming Chiao Tung University (NYCU). My research has been published in some decent journals, like Operations Research, IEEE Transactions, Computers in Industry, and the International Journal of Production Research. I earned my Ph.D. in Industrial Engineering from The Pennsylvania State University – University Park. I dived deep into the world of stochastic modeling and analytics and especially passionate about applying these techniques to smart manufacturing and service systems.
